CBaseRenderer::SendRepaint

The SendRepaint method sends a repaint event to the filter graph manager.

Syntax

void SendRepaint(void);

Remarks

This method sends an EC_REPAINT event to the filter graph manager if the following conditions are true:

• The input pin is connected.
• The filter is not flushing data.
• The end-of-stream was not reached.
• The CBaseRenderer::m_bAbort flag is FALSE.
• The CBaseRenderer::m_bRepaintStatus flag is TRUE.

Depending on the state of the graph, the EC_REPAINT event can cause the upstream filter to re-send a sample; the filter graph to seek to its current location; or the filter graph manager to pause momentarily. (See EC_REPAINT.) This event is potentially inefficient, so it should be used sparingly. However, video renderers sometimes need to refresh the display.
